You have something wrong with you mate!
Why do you feel the need to be constanly "in touch" with your friends.
Let's face it lightbulbs replaced candles.
Facebook wont replace telephonesor personal contact.
Worldwide - 2 billion internet users. 1 billion Facebook members.
Half of all internet users DONT use Facebook at all.
Facebook is the fastest growing internet platform. Half of internet users use it (by your stats that is). To many young people Facebook IS the internet.
in the next 5 years (at current rates of growth) FB will account for something like 65% of internet time. That's time spent online, not 65% of individul users.
Now let me guess, the refute will be along the lines of "yeah but 65% of time spent messing about by morons".
*sigh* I don't like it either but at least my eyes are open to how communication is heading.
